COMMAND RECEPTION CONFIRMING SYSTEM FOR RADIO COMMUNICATION SYSTEM

PROBLEM TO BE SOLVED: To provide a command reception confirming system in which communication efficiency is improved by shortening the time for collecting the command reception confirming signals after simultaneous communications from a control station to a plurality of mobile stations. SOLUTION: Serial numbers are imparted and set in advance to all the mobile stations in the groups which the mobile stations belong. After the simultaneous communications, the command reception confirming signals are sent once to prescribed groups in the manner of simultaneous communications. Thus, all the target mobile stations transmit the command reception confirming signals in the order of the serial numbers with a time point when the command reception confirming signals are received as a start point, and the control station collects the command reception confirming signals transmitted from the respective mobile stations in the order of serial numbers.
